The pillow cases seemed ok out of the package, However after washing them they were very rough. I do not believe for one second that these are really 300 thread count. They also have a petroleum smell to them that did not go away after washing. I threw them away. DO NOT BUY.
While I bought 2 sets in the fall, I was looking for extra pillow cases to exchange in between. The ones that arrived did not have the satin stripe at the end as shown. Instead in had a flap that was inserted so that the pillow is tucked in. Not necessarily a bad thing, but not as attractive as with the satin stripe. More importantly, the fabric on these pillow cases feels rough by comparison. I washed them before use, and have washed them 2-3 times since and they still feel rough--much more so than the originals that came with the sets. Disappointed.
We bought these to go with the sheet set we bought of the same Egyptian cotton 300 thread count ivory color and stripes. After one washing the cases held their form, didn't shrink too much and are only just a tid bit darker in color than the cases that came with the sheet set. The remain striped and silky soft just like the sheet. It was a good guess on the match and I'm very happy with them.
